NAME ^

Tk::More - a 'more' or 'less' like text widget

SYNOPSIS ^

    use Tk::More;

    $more = $parent->More(...text widget options ...);
    $more->Load(FILENAME);

DESCRIPTION ^

Tk::More is a readonly text widget with additional key bindings as found in UNI* command line tools more or less. As in more an additional status/command line is added at the bottom.

ADDITIONAL BINDINGS ^

Key-G or End

goto end of file

Key-f or Next

Key-b or Prior

backward screen

Key-k or Up

up one line

Key-j or Down

Key-d

OPTIONS ^

Name: fixedFont
Class: FixedFont
Switch: -font

Set the font of the viewer widget. This is by default a fixed font.

Name: searchCase
Class: SearchCase
Switch: -searchcase

Set if searching should be done case-insensitive. Defaults to true.

Switch: -helpcommand

Sets the command for the "h" (help) key.

METHODS ^

Load($file, %args)

Load $file into the widget. %args may be one of the following

-encoding => $encoding

Assume the encoding of the file to be $encoding. If none is given, then assume no encoding (which is equivalent to iso-8859-1).

AddQuitBindings

Convenience method to add the bindinds Key-q and Control-Key-q to close the Toplevel window containing this More widget.

BUGS ^

Besides that most of more bindings are not implemented. This bugs me most (high to low priority):

* better status line implementation

* Cursor movement: up/down move displayed area regardless where insert cursor is

* add History, Load, Search (also as popup menu)
